So i had my gopro hero 5 black on a camping trip and left it in my sleeping bag but i forgot to turn it off. When i came back the hero 5 was so hot i couldn't even touch it! Now that it has cooled down and i powered up my gopro with a 100% charged battery it seemed to drain the battery in ~15 min compared to 1.5 hours before the overheat. I tried it with a different battery and the same thing happened. It also has difficulty turning on and sometimes wont turn on at all unless i plug it into my computer! When i record something and edit it there is also this beeping noise in the background with a slight static noise.
